我在YAML 文件中进行了验证，它通过了，但是，当我尝试从此 YAML 文件 API 生成代码时，它返回以下错误：

openapi 生成器版本
  • 4.3.1
OpenAPI 声明文件内容或 url

网址代码：https ://github.com/platformsh/platformsh-client-java/blob/master/src/main/resources/api.yaml

用于生成的命令行

在这个项目源代码上：https ://github.com/platformsh/platformsh-client-java 我们运行这个命令：

mvn clean package
重现步骤 
git clone git@github.com:platformsh/platformsh-client-java.git
cd platformsh-client-java
mvn clean package
